POLE-COUPLING.

Patented (lot. 22, 1918.

Application filed September so, 1914; Serial No. 864,204.

To all whom it may concern:

Be it known that I, l/VILLIAM R. FARI- BAULT, a citizenof the United States, and

resident of Normandy, Missouri, have invented certain new and useful Improvements in Pole-Couplings, of which the following is a specification.

This invention relates to improvements in a pole coupling, which is especially adapted for tent poles or any ordinary extension pole and by which each section of the pole is inserted and firmly locked.

A further object of my invention is to construct a coupling which is designed to be used in connection with tent poles where the tent is to be of a portable nature and to be packed in a small and compact bundle.

Figure 1, is a side elevation of my improved coupling with a part broken away and in section.

Fig. 2, is a side View of my invention shown in the form of an Lcoupling.

Fig. 3, is a side view of a straight coupling embodying my invention showing the end of the pole to be inserted.

Fig. t, is an enlarged cross-sectional view taken on the line 4 1 of'Fig. 3, with the tent pole in position.

In carrying out my invention 1 construct a coupling consisting of a casting made either in the form as shown in Figs. 1, 2, or 3,-or at any other angle as may be found desirable depending upon the angle of the extension needed, and each casting consists of a body portion 5, which is cylindrical in form, its ends provided with a bayonet lock construction which is in the form of a slot 6,

the end provided with a bridge 7 the slot 6 then running at right angles as indicated by the numeral 8, and then terminating into approximate T-shaped slot 9.

On the pole 10, is located a ferrule 11, which is provided with an integral projection 12, or otherwise and the ferrule is held on the pole by means of a rivet, screw, or bolt 13. The projection 12, is so arranged as to freely slide into the slot 6, and pass beneath the bridge 7, which bridge is formed preferably integral with a casting acting as a brace and support to prevent the cylindrical body from spreading at that point.

The couplings as shown in Figs. 1 and 2, are provided with an integral projection 14, and which is used. in he suppo t o the tent covering and when a coupling of an angular nature such as shown in Figs. 1 and 2, is used, the bayonet look connection is located on the opposite side as that shown, but when the straight coupling is used as that shown in Fig. 3, the bayonet lock is located on the same side. The angular couplings as shown in Figs. 1 and 2 are provided with strengthening ribs or webs 15, to properly support the casting and to form a rigid support.

A coupling of this character is used in connection with a tent as that described and claimed and issued to me by Letters-Patent on tents, No. 1,095,272, May 5, 1914, and which permits a tent pole to be arranged in short sections so that the same can be easily and readily packed and occupy but little space.

The horizontal coupling may be used in connection with awning poles of great length, or any other purpose where a continuation of a pole is desired; and by means of the bayonet lock connection the poles when inserted in the couplings are firmly locked, and can only become disconnected when properly turning the coupling in such position as to permit the projection 12, on the ferrule to be brought in proper alinement with the inserting slot 6, otherwise, the lug-when in the T-shaped slot when raising in either the upper or lower projection of the slot will provide a rigid connection and prevent the same from becoming uncoupled.

Having fully described my invention what I claim is:

1. A coupling of the class described comprising an angular cylindrical casting, each end provided with a bayonet lock connection whereby the end of a pole may be inserted and locked therein and a vertical lug on the upper surface of the casting at the apex of the angle substantially as specified.

2. A coupling of the class described comprising a cylindrical body, the same being angular, the ends of said body provided with a bayonet lock connection in combination with a ferrule provided with a projection fastened to a pole; each ferrule projection is inserted in the hollow member and sup ported in the bayonet lock connection and alug formed on the upper surface of the angle substantially as specified.

3. A device of the class described comprising a ho low angular cylindrical body,

slots formed in the sides thereof in the fqrm In testimony whereofl I have signed my of a bayonet lock, a bridge for .snpportlng name totlns speclficatlon, in presence of two the member, a vertical lug formed on the top subscrlblng Witnesses.
